EARL C. POTTER, OF CHICAGO, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO

PORATION OF NEW YORK.

SEFTON MANUFACTURING CORPORATION, OF MILLIBROOK, NEW YORK. A COR- To allwhom it may concern: 7

Be it known that I, EARL J. Porrnn a citizen of the United States,residing at Clucago, Cook county, Illinois, have invented.

certain new and useful Improvements in Shipping-Boxes, of which thefollowing is a s ecification. p

y invention relates to shipping .boxes made of relatively fragilematerial, such as the well-known article commercially termed corrugatedpaper board, and is des gned to provide a box made of such materialsufficiently strong, and affordin sufiiclent protection to the inclosedfragile contents for which the package is designed, to enable the box tobe shipped by frei ht w1th relatlvely small loss by breakage. heembodiment of my invention which will hereinafter be described is a boxdesigned for shlpment of incandescent electric lamps, although it isobvious that b suitable modification of the proportions o the box andthe inside con- The inside containers or fillers are likewise designedto have a cushioning action and to so suspend the lam s that the lampsin ad acent containers wil bear on separate card'- 'board partitionsspaced a art a suflicient distance to avoid liability o the lampsbearing on each other through the partitions. My invention consists inthe construction and -arrangement of cooperating structural members bywhich I'sec'ure the above and incidental advantages and attain theobject hereinbefore stated, the essential elements thereof being recitedin the appended claims.

.-In the drawings, Figure 1 is a erspective view of my box, with thecover aps of the outer shell opened out and the top cover of the insideshell removed; Fig. 2 is a similar view, but with the top covermentioned removed; Fig. 3 is a perspectiveof Specification 01 Letters1mm. t t Jun, 1920 Applicatitn'flled February 21, 1918.

the top cover alone; Fi 4' is a vertical section on the line 44'o Fig.5; Fig. 5 is a llorlzontal section on-the line 5-5 of Fig.

4; Fig. 6 is a perspective of one of the in-- same parts in all thefigures of the drawing.

The outer shell of my package, as before stated, is of ordinaryconstruction, and comprises four side members, 1, 2, 3 and 4, and endflaps 5, 6, 7, and 8, preferably formed of one rectangular sheet ofmaterial creased and folded to form a four-sided shell, a hinge strip 9being provided to unite the meetin edges of the sides 1 and 4, and thecover aps being adapted to fold inwardly 0 form top and bottom wallsclosing the The inner shell consists of the four sides 10, 11,12 and 13hinged together to form a four-sided shell, the meeting edges of thesides 10 and 13 being secured together by a hinging strip 14. The sides,as shown, are cut away to leave projecting ton ues or tenons 15, both attop and bottom, t e ends of the box being of the same construction. Theends or top and bottom cover members of the inner box consistofrectangular sheets of material 16 of such-size as to fit snugly withinthe sides of the outer box and are formed with slots or mortises 17 toreceive the tenons -before mentioned. The edges of the cover areprovided with spacing flanges 18 which are of such heights as to contactthe innermost cover flaps of the outer shell when the cover is firmlyseated on the lower line of the cut away portions of the sides of theinner shell intermediate its tenons, and the tenons themselves are ofsuch length as to also contact the sides, this construction providing aninner chamber or receptacle strongly supported at the edges of the topand bottom of the package, its most vulnerable points.

The containers 'or fillers in which the lamps are contained in smalllots, in the Freferpresent instance in lots of five, are

rial, a suitable material for the purpose being thin but tou h manilacardboard. This container (see Figs. 6, 7 and 8) comprises four sides19, 20, 21 and 22, and flaps forming top and bottom closures which areof similar, though not identical construction. The side 21, it may behere explained, is provided with a hinge flap 23 by which it is securedto the side 20, the other sides and flaps being formed by creased foldinlines which permit the parts to be folde and arranged in the mannerillustrated and herein explained. At the top of. the front side wall 19of the container is hinged the side flange 24 of a depressed or sunkenpartition 25, which is formed with side flanges 24 and 26, and endflanges 27, 28. The partition 25 is formed with a series of properlyspaced holes of two sizes, the holes of one size being each adapted toreceive the reduced end of the neck of an incandescent lamp, and theother and smaller holes being each adapted to receivethe end of theglass bulb of the lamp. The end side walls 20 and 22 are provided withhinged supporting fiaps 29 adapted to be folded inwardly above thepartition 25, in which position'their bases will afford considerablesupport to the sides of the cover flap 30, which flap is hinged to therear side wall 21. At its front the cover is provided with a fasteningtab 31- adapted to be inserted in a slit 32, cut to receive it in thefront wall 19, and a pair of spacing and supporting flanges 3232 adaptedto fold down adjacent the flanges 24 and rest upon the top of thepartition 25. The bottom closure of the container is formed in the samemanner as the top, differing only in the arrangement of the holes toreceive the lamps, which must be reversed in respect to the two sizesinorder to provide for the arrangement of the lamps with the basesalternately up and down as illustrated; and in the provision of alocking flap or tab 33 which will resist disengagement hinged to thebottom cover 34 instead of the readily disengageable tab 31 used at thetop of the container. It is, however, obvious that the bottom of thecontainer may be permanently closed by pastin adjacent parts together,if desired.

he containers are designed to be placed upright in tiers in thepackage,-that is, with the closures of the containers and outer shell ofthe box all in parallel planes, as indicated in Figs. 4 and 5. Thepackage having been closed, the cover flaps 5 and 7 of the outer shellare folded inwardly over the topsof the tenons of the inner shell, andthe flaps 6 and 8 next folded down, in which position their edges meettightly. A strong sealing tab is then pasted along said edges and downupon the sides of the box, so that it is practically hermeticallysealed. The result of this construction is that the inner shell and itscontainers are pneumatically cushioned to a considerable extent. It mayfurther be noted that the joints around the flanged sides of the coverand the mortise joints are practically air tight, dividing the spacebetween the outer and inner shells into three separate air tightcompartments, the intermediate one of which extends entirely around thecontainer chamber of the inner shell. j

I claim:

1. A shipping box comprising an outer rectangular shell, an inner shellconsisting of four side walls hinged together, spaced from the outershell, a cover member arranged adjacent and parallel with one of thewalls of the outer shell and adapted to fit snugly within the foursurrounding walls of such outer shell, said cover member being arrangedto interlock with the ends of the sides of the inner shell and form aclosur for the same.

2. A shipping box comprising an outer rectangularshell, an inner shellhaving the free ends of its sides formed with tenons and spaced from theouter shell consisting of four side walls hinged together and a covermember arranged adjacent and parallel with one of the walls of the outershell and adapted to fit snu ly within the four surrounding walls of t esame, said cover member being formed with mortise openings to receivesaid tenons and constituting a closure for said inner shell. V

3. A shipping box comprising an outer rectangular shell, an inner shellspaced from the outer shell consisting of four side walls hingedtogether, a flanged cover member arranged adjacent and parallel with oneof the walls of the outer shell and having its flanges arranged to bearagainst such wall, said cover member being adapted to fit snugly Withinthe four surrounding walls of the outer shell and interlock with theends of the sides of. the inner shell to form a closure for the same.
